Responding to complaints from users, MTN Nigeria said the “NIMC application is currently unavailable.

“Please bear with us as we are unable to process sim swap and upgrade requests at the moment. Feedback will be shared as soon as the issue is resolved. Apologies for the inconvenience this may cause you.”

Meanwhile in a statement on Saturday, the NIMC confirmed the problem, which it attributed to ongoing maintenance.

“The National Identity Management Commission (NIMC) wishes to inform the general public that its NIN verification Service (NVS) is temporarily unavilable due to the maintenance service being carried out by one of the Commission’s network service providers,” the statement said.

“The NIMC wants to assure the public that verification and authentication services would be restored once the maintenance is concluded.

“The Commission apologises for any inconvenience this might cause our esteemed customers, as all hands are on deck to ensure speedy restoration.

“Meanwhile, the public can make use of the alternative Tokenisation verification platform.”

‘Loss of trust’

The affected NIMC portal allows third parties to confirm the identity of customers.

Apart from telecoms firms, financial institutions and government agencies also rely on the service.

“The biggest implication is the loss of trust,” said technology analyst Fred Agbata. “People who depend on things manually are told technology is a better option, but then downtimes can make their lives more miserable.”

Agbata also noted that the NIMC downtime should lead to questions about how safe the system is in protecting the information of millions of Nigerians.

Last month a hacker identified as Sam claimed he had found a bug on the NIMC server that could be used breach the system.

The NIMC at the time debunked the hacker’s claims.

“Over the years, through painstaking efforts, NIMC has built a robust and credible system for Nigeria’s identity database,” a spokesperson said.

NIN-SIM linkage

The linkage of NINs and SIMs was mandated by the Federal Government, through the Ministry of Communications and Digital Economy, as part of efforts to build a cohesive national database.

Although the process was hampered by long queues and massive crowds amid COVID-19 restrictions, forcing the government to serially extend the deadline for the linkage, the NIMC has said it is committed to its mandate to establish, own, operate, maintain and manage the National Identity Database in Nigeria.

All other forms of identity management, including the Bank Verification Number (BVN), are expected to be lined to the NIN.
